. the following is 'a specification.

This invention is awaterinobile, and the obect of the invention is a water craft which wi l travel upon the surface of the water, bein propelled by suitable paddles but which wi l have practically nov draft beyond the depth of the paddles being provided with an aerial plane which will prevent the device sinking intolthe water thereby'relieving it of `the 'resistance of the water which must be overcome by a vessel which` is partially submer d.l

T e invention consistsof the novel features of construction hereinafter described,

pointed out iithe claims, and shown in the accompanying drawings in which Y Figure 1 is a side elevation. Fig. 2 is a rplan view.

In constructing a device "of this kind I employ a frame 1 above which is arranged a suitable platform 2,' and at each end of the frame I arrange rotatable hollow airtight cylinders 3 designed to rest upon the 'surface of the water and provided' with paddles 4. A motor 5 is placed upon the platform and' a sprocket cha'in 6 runs over a s rocket wheel 7 on the motor shaft and/ .a so over asprocket wheel 8 on a power shaft 9 which sha-ft is jouriia-led transversely in the frame 1 midway7 its ends. A sprocket chain 10 runsj the ength of the frame on each'side and .over sprocket wheels 11 carried by the ends of the cylinders 3 said sprocket chains being driven by engagement with the sprockets of sprocket wheels 10a.

'A device constructed as above described would float upon the water but owing to the weight of the parts referred to would re- -qiiire cylinders 3 lof considerable size which cylinders would also. be more or less conipletely submer ed in the water. In ord'er l that the cylin ers may oat as nearly as U rights 12 are of tli possible upon thesurfa'ce of the water the f ollowing means for lifting aportion of the weight of the device from the water is employed.

hinges the upper sections are bent -inwardly and are carried lto .a point about the center of the platform 2 and are then bentrfslightly downwardly formin `an invertedbow as f n aerial plane- 14 is hingedupon the horizontal portiofrip, ofthe uprights 13 and is guided in its vertical or swinging 'movement bythe uprights 12. permit adjustment ofthe aerial plane, I probent to forni projecting pins 20 which enf gage the slots 18 of the angled' portions ofthe shaft 16. The aerial plane is braced byv cross wires 22 and is provided with a c0v ering 28 of any suitable'light material. A rudder 24 is pivotally mounted in the U-shaped or bow portion of the rear up-A rights 13. The operation ofthe device will be obvious from the description given of the construction. f

By operatinr the handles 17 the aerial plane can be lifjted upwardly at the forward end so as to set at an angle to theV platform 2, this lifting of the aerial plane being permitted by the hinges 14. When lifted as inl dicated by the dotted lines in Fig. l it will act as a guide and the pressure of the air upwardly upon .the under surface of the 1.
